PROCESS FOR PREPARING A PET FOOD COMPOSITION
FIELD OF THE INVENTION
[0001] This invention is directed generally to processes for preparing pet
food
compositions and particularly to processes for preparing restructured meat and
meat-analogue pieces.
BACKGROUND OF THE INVENTION
[0002] Animals have been fed "dry" and "wet" food compositions for many years.
"Wet" food compositions are generally packaged in can-like containers and are
considered
"wet" in appearance because of the moisture contained therein. Two types of
wet food
products are generally known in the art. The first is known in the art as
either a "minced"
or "ground loaf' product. Loaf products are typically prepared by contacting a
mixture of
components under heat to produce an essentially homogeneous, intracellular
honeycomb-
type mass or "ground loaf." The ground loaf mass is then packaged into a
cylindrical
container, such as a can. Upon packing, ground loaf assumes the shape of the
container
such that the ground loaf must be cut when serving to an animal. As a result
of processing,
ground loaf products exhibit a wide range of textural differences and loaf
products
generally do not mix well with other forms of foods, especially dry products.
[0003] Another type of wet product is generally known in the art as "chunk
and gravy."
Chunk and gravy products comprise restructured meat pieces prepared by making
a meat
emulsion which is first extruded and formed or "set" by physical pressure or
thermal
energy such as cooking with steam, cooking in water, frying in oil, oven dry
heat and the
like. The product pieces are eventually mixed with a gravy or sauce in a
container, usually
a can, which is then seamed and sterilized. As opposed to ground loaf, chunk
and gravy
products have physically separate, discrete chunks as prepared. These discrete
particles
are present in the gravy-type liquid in the final container. When serving,
chunk and gravy
products flow out of the can and can be easily mixed with other dry products.
[0004] These types of wet pet food compositions generally require high
amounts of
protein to form the desired product type as the thermal processing "sets" the
product
through protein denaturation.
[0005] There is, therefore, a need in the art for improved methods of
making a food
composition comprising restructured meat pieces and meat analogue pieces. More
specifically, there is a need in the art for a method of making aesthetically-
pleasing

PCT/US2011/056343
restructured meat pieces and meat analogue pieces, where that method utilizes
a gelation
effect in the formation of restructured meat chunks to solidify protein/starch
matrices,
resulting in a process that is less dependent on protein content for
structural integrity of the
meat chunk.

DETAILED DESCRIPTION OF THE INVENTION
[0015] The following description of the preferred embodiment(s) is merely
exemplary
in nature and is in no way intended to limit the invention, its application,
or uses.
[0016] In one aspect, the present invention provides a process for
preparing a food
composition. In one embodiment, the process comprises a method for preparing a
food
product that comprises (a) mixing a dry ingredient composition, a protein-
containing
composition, and an alginate composition to provide a first mixture; (b)
mixing the first
mixture with a setting composition to effect a gelation reaction, wherein the
setting
composition comprises a source of calcium ions; and (c) processing the product
of the
gelation reaction to provide the food product. wherein the food product has a
stable
striicture prior to retort.
[0017] As used herein, the phrase "restructured meat piece" refers to
the shaped
products of the method disclosed herein that comprise meat components from one
or more
sources that have been formed into stable structures that resemble animal
muscle pieces in
3b
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
one or more of size, shape, texture, color, and flavor. The restructured meat
pieces of the
present disclosure may further comprise proteinaceous material from non-animal
sources,
but the proteinaceous material is predominantly of animal origin.
[0018] As used herein, the phrase "restructured meat analogue piece" refers
to a
restructured meat piece prepared by the method of the disclosure in which the
predominant
amount of proteinaceous material is from non-animal sources. In various
embodiments,
the restructured meat analogue pieces, substantially all of the proteinaceous
material is
from non-animal sources. Accordingly, the proteinaceous material of the
restructured
meat analogue pieces of the disclosure may comprise, consist essentially of,
or consist of
non-animal proteinaceous material.
[0019] As used herein, the phrase "striated structure" indicates that faces
of
restructured meat and meat analogue pieces of the present disclosure possess
visible bands
or striations that resemble the patterns created by the parallel fibers of
skeletal muscle.
[0020] In one embodiment, the food product of the method is a restructured
meat or
meat-analogue piece that is structurally stable prior to retort. In a further
aspect of this
embodiment, the restructured meat pieces or meat analogue pieces are
irregularly shaped,
while in another aspect the restructured meat pieces or meat analogue pieces
are irregularly
shaped and/or have a striated structure.
[0021] The food products produced according to the present disclosure can
be
nutritionally and organoleptically adapted for consumption by any animal,
including a
human. In certain embodiments the food product of the present disclosure is
nutritionally
and organoleptically adapted for animals of the order Carnivora, e.g., for a
feline or canine
animal.
[0022] The size of the restructured meat pieces and restructured meat
analogue pieces
prepared by the methods of the present disclosure will be consistent with the
intended use.
For example, where the meat and meat analogue pieces are intended for use in a
chunk-and-gravy canine food composition, each dimension of the piece can have
a value
independently selected from within a range of from about 5 to about 50 mm,
within a
range of from about 7.5 to about 45 mm, within a range of from about 10 to
about 40 mm,
within a range of from about 12.5 to about 35 mm, and within a range of from
about 15 to
about 30 mm. These size ranges can be adjusted up and down depending, e.g, on
the size
and age of the animal for which the food is intended. Where the food product
is intended
4
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
for a feline, for example, the size ranges of the restructured meat pieces and
restructured
meat analogue pieces prepared by the methods of the present disclosure will
generally be
selected from among the lower size ranges indicated for canines.
[0023] In other embodiments in which where the meat and meat analogue pieces
are
intended for use in a hash-, minced-, loaf-, or hybrid-type food composition,
in which
each dimension of the piece can have a value independently selected from
within a range
of from about 1 to about 17.5 mm, within a range of from about 2 to about 15
mm, within
a range of from about 3 to about 12.5 mm, within a range of from about 4 to
about 10 mm,
and within a range of from about 5 to about 8 mm. These size ranges can be
adjusted up
and down depending, e.g, on the size and age of the animal for which the food
is intended.
Again, where the food product is intended for a feline, for example, the size
ranges of the
restructured meat pieces and restructured meat analogue pieces prepared by the
methods of
the present disclosure will generally be selected from among the lower size
ranges
indicated.
[0024] In certain embodiments, the dry ingredient composition may comprise
pre-ground cereal grains and fibers, and may further comprise suitable vitamin
mixtures,
mineral mixtures, colorants, trace calcium sequesterants, and minor nutrients.
In one
illustrative aspect of this embodiment, the calcium sequesterant is sodium
tripolyphosphate. In another aspect, the minor nutrients may include, but are
not limited
to, taurine, choline, carnitine, and combinations thereof. The specific
components of the
dry ingredient composition, identified in a specified formula, are weighed and
mixed
together to provide the dry ingredient composition. In certain embodiments,
e.g., those in
which the formula specification provides for a non-animal proteinaceous
material, such as
defatted soy flour, rice flour, wheat flour and the like, may be included in
the dry
ingredient composition rather than in the protein-containing composition.
Accordingly,
the terms protein-containing composition and dry ingredient composition are
not
necessarily intended to be mutually exclusive; i.e., as above, some specific
materials may
be included in one or the other ¨ or both ¨ of the protein-containing
composition and dry
ingredient composition.
[0025] In certain embodiments, the protein-containing composition comprises
meat and
meat by-products. In this aspect of the disclosed method, for example, frozen
meat and
meat by-products blocks are ground through a 0.32 cm to 1.27 cm plate using
conventional
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
meat processing equipment to provide the protein-containing composition. When
present,
suitable meat and meat by products may be selected from but are not limited to
pork liver,
chicken, and pork lungs. In other aspects of this embodiment, protein-
containing
composition can be prepared to include animal protein available from a wide
variety of
additional meats and meat sources including, for example, those selected from
the group
consisting of animal muscle, animal skeletal meat, animal by-products, and
mixtures of
muscle, skeletal meat and by-products. Meats include, for example, the flesh
of poultry, fish,
and mammals (e.g., cattle, swine, sheep, goats, and the like). Meat by-
products include, for
example, lungs, kidneys, livers, tongues, stomachs and intestines. Suitable
meat sources may
include fresh and frozen meats or meat by-products. In certain embodiments,
the meat
component of the protein-containing composition is generally prepared by
grinding the
meat through different grind-plates, typically ranging from about 1.27 cm to
about 2.54 cm
in size, to form discrete food particles.
[0026] The meat mixture incorporated into a protein-containing composition
used in
the present methods may be prepared in any suitable mixing apparatus known to
one
skilled in the art. Non-limiting examples of suitable apparatus for preparing
the meat
component include a twin screw mixer, a twin ribbon mixer, an overlapping
paddle mixer,
or a combination mixer such as a screw/ribbon/paddle.
[0027] In a specific embodiment, the protein-containing composition can
include egg
whites, either as a fluid component or as dried egg whites. In other
embodiments, the
protein-containing composition may include, consist essentially of, or consist
of
non-animal proteinaceous materials, including but not limited to defatted soy
flour, rice
flour, corn flour, wheat flour, barley flour, rye flour, vegetable protein,
protein
hydrolysates, and combinations of two or more thereof. The protein-containing
composition may include, consist essentially of, or consist of animal protein
sources
including but not limited to, poultry, beef, lamb and fish.
[0028] Alginates are hydrophilic derivatives of alginic acid, a
polysaccharide composed
of beta-D-mannuronic acid residues linked so that the carboxyl group of each
unit is free,
while the aldehyde group is shielded by a glycosidic linkage. Alginates
suitable for use in
the present methods include alkali metal alginate salts such as potassium and
sodium
alginate, and mixtures thereof. The alginate composition of the present
disclosure is
generally a suspension, hydrocolloid, or solution prepared by contacting a
suitable
6
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
alginate, e.g., potassium or sodium alginate, with water. In one embodiment,
this can be
accomplished using an in-line or batch-type high-shear mixer. In certain
embodiments,
dissolution of the alginate can be facilitated by contacting the alginate with
an oil-based
component of the composition. In one aspect the oil-based component is soybean
oil. In
certain embodiments sodium or potassium alginate is present in the alginate
composition
at a weight % level (as compared to the total weight of the alginate
composition) within
the range of from about 0.1 to about 10%, from about 0.25 to about 9%, from
about 0.5 to
about 8.5%, from about 0.75 to about 8%, from about 1 to about 7.5%, from
about 1.25 to
about 7%, from about 1.5 to about 6.5%, from about 2 to about 6%, from about
2.5 to
about 5.5%, and from about 3 to about 5%. In a specific embodiment, sodium or
potassium alginate is present in the alginate composition at a level of about
4% on a
weight basis.
[0029] In certain embodiments the alginate composition comprises an oil,
e.g., soybean
oil. When present, the oil is included in the alginate composition at a weight
% level (as
compared to the total weight of the alginate composition) within the range of
from about
0.1 to about 10%, from about 0.25 to about 9%, from about 0.5 to about 8.5%,
from about
0.75 to about 8%, from about 1 to about 7.5%, from about 1.25 to about 7%,
from about
1.5 to about 6.5%, from about 2 to about 6%, from about 2.5 to about 5.5%, and
from
about 3 to about 5%. In a specific embodiment, the oil is soybean oil and is
present in the
alginate composition at a level of about 4% on a weight basis.
[0030] In one embodiment, the setting composition is a solution, which may
comprise
divalent-cation containing salts, including but not limited to calcium
chloride, calcium
lactate, calcium lactate gluconate, dicalcium phosphate (i.e., calcium
monohydrogen
phosphate or dibasic calcium phosphate; either as the dihydrate or anhydrous
form),
calcium sulfate or calcium carbonate. Although salts of strontium, barium,
nickel, lead,
cadmium, and cobalt are also useful in gelation reaction, such salts have
limited usage in
food applications due to toxicity. In other specific embodiments, one or more
of the
aforementioned salts are combined with water and one or more materials
selected from
among a gum, e.g., guar gum, to adjust viscosity, a liquid palatant, and a dry
palatant.
[0031] In other embodiments, the setting composition is a solution
comprising one or
more of calcium chloride, calcium lactate, calcium lactate gluconate,
dicalcium phosphate,
calcium sulfate, and calcium carbonate.
7
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
[0032] In certain embodiments the setting composition comprises calcium
chloride at a
weight % level (as compared to the total weight of the setting composition)
within the
range of from about 0.25 to about 20%, from about 0.5 to about 17.5%, from
about 1 to
about 15%, from about 1.5 to about 14.5%, from about 2 to about 14%, from
about 2.5 to
about 13.5%, from about 3 to about 13%, from about 3.5 to about 12.5%, from
about 4 to
about 12%, from about 4.5 to about 11.5%, from about 5 to about 11%, from
about 5 to
about 10%, and from about 6 to about 9%.
[0033] In certain embodiments the setting composition comprises anhydrous
dicalcium
phosphate at a weight % level (as compared to the total weight of the setting
composition)
within the range of from about 0.05 to about 10%, from about 0.1 to about 9%,
from about
0.25 to about 8.5%, from about 0.5 to about 8%, from about 2 to about 14%,
from about
2.5 to about 13.5%, from about 3 to about 13%, from about 1 to about 7.5%,
from about
1.5 to about 7.5%, and from about 2 to about 6.5%. In a specific embodiment,
anhydrous
dicalcium phosphate is present in the setting composition at a level of about
4% on a
weight basis. Where the dehydrate form of dicalcium phosphate is employed, it
is used at
levels proportionately higher than the levels of the anhydrous material.
[0034] In certain embodiments, the rate of the gelation is controlled, at
least in part, by
adjusting the pH level, e.g., in the first mixture, and including one or more
of calcium
chloride, dicalcium phosphate, calcium sulfate, and calcium carbonate in the
setting
composition. In another aspect of these embodiments, the rate of the gelation
is
controlled, at least in part, by the inclusion of calcium ion sequesterants.
In a further
aspect of these embodiments, the rate of the gelation is controlled, at least
in part, by the
inclusion of encapsulated calcium sources such as encapsulated calcium
lactate. In other
aspects of these embodiments, the rate of gelation is controlled by adjusting
more than one
of the above variables.
[0035] In certain embodiments, the gelation reaction is controlled in such
a manner that
the process of the present disclosure can be run as a continuous process and,
in one aspect
of this embodiment, the process of the present disclosure can be run as a
largely-automated, continuous, commercial-scale process.
[0036] In certain embodiments the food product is combined with a gravy to
provide,
e.g., a chunk and gravy composition, a hash-type food, a minced-type food, a
loaf-type
food, or a hybrid-type food pet food composition. The gravy may comprise one
or more of
8
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
the following components: starches, gums, colorants, emulsifiers, salts, and
palatants. In
specific embodiments, the gravy components are hydrated in a high shear mixer
with the
amount of water, as set forth in the formulation. If necessary or desired,
e.g., where the
gravy is starch-based, the resulting composition can be cooked to
approximately 82 C.
[0037] In certain embodiments, the viscosity of the gravy is sufficient to
suspend the
restructured meat and meat analogue pieces throughout a filling and canning
operation to
ensure a consistent ratio of such pieces to gravy, e.g., in a 'one stage'
container-filling
process in which a composition comprising both the gravy and the restructured
meat and
meat analogue pieces are added directly to the container or can. In other
embodiments,
e.g., "two-stage" filling processes, the gravy and the restructured meat and
meat analogue
pieces are added to the containers separately. In one aspect of the latter
process, the
restructured meat and meat analogue pieces are deposited in the containers or
cans in a
first step that is followed by a second, gravy-deposit, step.
[0038] In certain embodiments, the pet food composition comprises sodium or
potassium alginate. The sodium or potassium alginate is present in pet food
composition
at a weight % level (as compared to the total weight of the pet food
composition) within
the range of from about 0.01 to about 5%, from about 0.05 to about 4.5%, from
about 0.1
to about 4%, from about 0.25 to about 3.5%, and from about 0.5 to about 3%. In
a specific
embodiment, sodium or potassium alginate is present in the pet food
composition at a level
of about 0.5% on a weight basis.
[0039] In certain embodiments, the pet food composition comprises a source
of calcium
ions contributed from the setting composition. The source of calcium ions
contributed
from the setting composition is present in the pet food composition at a
weight % level (as
compared to the total weight of the pet food composition) within the range of
from about
0.01 to about 5%, from about 0.05 to about 4.5%, from about 0.1 to about 4%,
from about
0.25 to about 3.5%, and from about 0.5 to about 3%. In a specific embodiment,
the source
of calcium ions contributed from the setting composition is present in the pet
food
composition at a level of about 0.5% on a weight basis. In a specific
embodiment, the
source of calcium ions is calcium chloride.
[0040] In certain embodiments the components combined in the methods of the
present
disclosure include a dry ingredient composition, a protein-containing
composition, an
alginate composition, and a setting composition, which are combined and
processed to
9
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
provide a food product. In one aspect of this embodiment, the dry ingredient
composition,
the protein-containing composition, and the alginate composition are each
prepared
separately, e.g., in parallel, and then combined and mixed to provide a first
mixture. In
this instance, the weight ratio of the mixture includes, on a weight % basis
(as compared to
the total weight of the food product), about 20% dry ingredient composition,
about 50%
protein containing composition, and about 10% alginate composition, to provide
the first
mixture representing approximately 90% of the total weight of the food
product. The first
mixture and the setting composition are then combined with the latter
representing
approximately 10% of the total weight of the food product.
[0041] In one embodiment, the first mixture and the setting solution are
combined
using a helical static mixer fitted with a "T-pipe" inlet. In one aspect of
this embodiment
the first mixture and setting solution are separately pumped into the helical
static mixer at
relative metered rates of 9:1, i.e., nine parts of mixture to one part of
setting solution to
initiate the controlled-rate gelation reaction involving creation of ionic
bonds between
alginate polymers mediated by the divalent cations of the setting solution.
The rate of the
gelation reaction is controlled by attention to the variables identified
above, including, for
example, the pH of the first mixture, the concentration of alginate in the
first mixture, the
concentration and pH-dependent solubility of the divalent-cation-containing
salts of the
setting solution, and the concentration, and avidity of any divalent metal ion
sequestering
agents that are present in the mixture. The addition of the alginate
composition to the
setting composition forms a structurally stable food product prior to retort
and does not
require a pre-retort or heating and cooling cycle. In one aspect of this
embodiment, the
folding action of the helical static mixer produces a striated, meat-like
appearance in the
formed food product extruded from the mixer. Traditional mixers such as a
ribbon or
paddle mixer, or other forms of mixing apparatus such as a progressive cavity
pump, do
not produce the striated meat-like appearance.
[0042] In one embodiment, the food product extruded from the mixer is cut with
a
variable speed knife to provide the food product in the form of variable-
length strips or
blocks. In another aspect of this embodiment, the product of the gelation
reaction,
extruded from the static helical mixer is conveyed to a multi-dimensional
dicer where both
length and width can be altered to provide irregularly-shaped restructured
meat pieces and
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
irregularly-shaped restructured meat analogue pieces having dimensions
suitable for the
intended use of the food product.
[0043] In a still further aspect of this embodiment, the formed, sized, and
shaped meat
and meat-analogue pieces prepared according to the disclosed method are
combined with
gravy and one or more optional inclusions selected from among vegetables,
pasta, grains,
rice and legumes, e.g., potatoes, carrots, peas, peppers and the like, each by
weight in their
respective formula amounts. The components are mixed, using for example a
single
ribbon, double ribbon, or planetary mixer, to provide a homogenous mixture,
which can
then be pumped to a can line seamer and filler. The cans are then sealed and
heated
(retorted) according to conventional practice. In an alternative aspect, the
formed, sized,
and shaped meat and meat-analogue pieces prepared according to the disclosed
method are
added directly to containers, e.g. cans, after which the gravy-optional
inclusion mixture
subsequently deposited before sealing and retorting.
[0044] In another embodiment, the formed, sized, and shaped meat and meat-
analogue
pieces prepared according to the disclosed method are flash frozen to provide
a preserved
food product. In one aspect of this embodiment, the formed, sized, and shaped
meat and
meat-analogue pieces prepared according to the disclosed method are combined
with gravy
and one or more optional inclusions before flash-freezing.
[0045] In another embodiment, the formed, sized, and shaped meat and meat-
analogue
pieces prepared according to the disclosed method are transferred to suitable
plastic bags
and vacuum-cooked, generally according to conventional sous-vide methods. In
one
aspect of this embodiment, the formed, sized, and shaped meat and meat-
analogue pieces
prepared according to the disclosed method are combined with gravy and one or
more
optional inclusions and transferred to suitable plastic bags and vacuum-
cooked, generally
according to conventional sous-vide methods.
[0046] In another embodiment, the components combined in the method of the
present
disclosure include a dry ingredient composition, a protein-containing
composition, an
alginate composition, and a setting composition, which are combined and
processed to
provide a "hash-," "minced-," "loaf-," or "hybrid-type" food product. These
food products
differ from the "chunk" and "chunk and gravy" food products primarily with
respect to the
smaller finished size of the restructured meat pieces and restructured meat-
analogue
pieces.

CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
[0047] In one aspect of this embodiment, the dry ingredient composition,
the
protein-containing composition, and the alginate composition are all mixed
together to
provide a homogeneous mass using, for example, a single or double ribbon
mixer, a
horizontal mixer with a single blade, or a planetary mixer. In one aspect of
this
embodiment, a metered stream of the setting composition is added to the mixer
while the
dry ingredient, protein-containing composition, and alginate compositions are
mixing, to
initiate and maintain a controlled-rate gelation reaction. The rate of the
gelling reaction is
controlled, e.g., by the pH of the composition, the concentration of alginate,
and the
concentration and pH-dependent solubility of the divalent-cation-containing
salts of the
setting solution. In this embodiment, mixing is continued to shape and size
the food
product to the desired structure for inclusion in the "hash-," "minced-,"
"loaf-," or
"hybrid-type" food product intended. Again, the weight ratio of the mixture
includes, on a
weight % basis (as compared to the total weight of the food product), about
20% dry
ingredient composition, about 50% protein containing composition, about 10%
alginate
composition, and about 10% setting composition, expressed as % of the total
weight of the
food product.
[0048] In one embodiment, the smaller-sized shaped meat and meat-analogue
pieces
are combined with a gravy or with both a gravy and inclusions, and the
combination mixed
until homogeneous. In one aspect of this embodiment, the mixed "hash-,"
"minced-,"
"loaf-," or "hybrid-type" food product is then pumped to suitable containers,
e.g., cans,
which are sealed and retorted generally according to conventional procedures.
In another
aspect of this embodiment, the mixed "hash-," "minced-," "loaf-," or "hybrid-
type" food
product is transferred to suitable plastic bags and vacuum-cooked, generally
according to
conventional sous-vide methods.
[0049] The dry ingredient composition comprises a mixture of one or more
carbohydrate sources. Suitable carbohydrate sources include, for example,
carbohydrates
selected from the group consisting of oat fiber, cellulose, peanut hull, beet
pulp, parboiled
rice, corn starch, corn gluten meal and mixtures thereof. It is important to
note that by
properly balancing carbohydrate sources, one skilled in the art can manipulate
the texture
of the final product. For example, short chain polysaccharides tend to be
sticky and gooey
and longer chain polysaccharides are less sticky and gooey than the shorter
chain.
Accordingly, the texture of food product can be influenced by the use, e.g.,
of longer chain
12
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
polysaccharides and modified starches, including native or modified starches,
cellulose
and the like. The carbohydrate can be included in the composition in an amount
of about
25% to about 90% by weight of the composition.
[0050] The dry ingredient composition may additionally comprise optional
components
such as added salt, spices, seasonings, vitamins, minerals, flavorants,
colorants, and the
like. The amount of such additives is at least partially dependent on the
nutritional
requirements for different life stages of animals. Contemplated vitamins
generally useful as
food additives include, for example, vitamin A, vitamin Bl, vitamin B2,
vitamin B6, vitamin
B12, vitamin C, vitamin D, vitamin E, vitamin K, biotin, folic acid, inositol,
niacin, and
pantothenic acid. Contemplated minerals and trace elements generally useful as
food
additives include, for example, calcium, phosphorus, sodium, potassium,
magnesium,
copper, zinc, choline, and iron salts.
[0051] In one embodiment, a pet food composition according to the present
disclosure
that comprises a food product prepared by the methods disclosed herein,
provides a
substantially nutritionally complete diet for an animal; i.e., a diet that
includes sufficient
nutrients for maintenance of normal health of a healthy animal on the diet.
[0052] The animal to which the composition is fed can be human or non-human.
In
various embodiments, the animal is a vertebrate, for example a fish, a bird, a
reptile or a
mammal. Illustratively among mammals, the animal can be a member of the order
Carnivora, including, without limitation, canine and feline species.
[0053] In a particular embodiment, the animal is a companion animal. A
"companion
animal" herein is an individual animal of any species kept by a human
caregiver as a pet,
or any individual animal of a variety of species that have been widely
domesticated as pets,
including dogs (Canis familiaris) and cats (Felis domesticus), whether or not
the
individual animal is kept solely or partly for companionship. Thus, "companion
animals"
herein include working dogs, farm cats kept for rodent control, etc., as well
as pet dogs and
cats.
[0054] Notwithstanding these illustrative embodiments, the methods of this
invention
also are generally suitable for the preparation of food products and food
compositions for
other mammals, including non-human mammals such as non-human primates (e.g.,
monkeys, chimpanzees, etc.), companion and working animals (e.g., horses,
etc.), farm
animals (e.g., goats, sheep, pigs, cattle, etc.), and wild and zoo animals
(e.g., wolves,
13
CA 02851544 2014-04-08
WO 2013/055360
PCT/US2011/056343
bears, deer, etc.). The methods of this disclosure also are generally suitable
for preparation
of food products and food compositions for use with non-mammalian animals,
such as
companion, farm, zoo, and wild birds, (including, for example, song birds,
parrots, ducks,
geese, chickens, turkeys, ostriches, etc.).
EXAMPLES
[0055] This invention can be further illustrated by the following examples
of particular
embodiments thereof, although it will be understood that these examples are
included
merely for purposes of illustration and are not intended to limit the scope of
the invention
unless otherwise specifically indicated.
[0056] The Examples describe the preparation of pet food compositions
comprising
food products prepared by the method disclosed herein. The Examples include
the
preparation of dry ingredient, alginate, setting, protein-containing, and
gravy compositions,
the combination of the dry ingredient, alginate, and protein-containing
compositions to
provide a first mixture, mixing of the first mixture with a setting solution
to effect a
gelation reaction product, wherein the setting solution comprises a source of
calcium ions,
processing of the gelation reaction product to provide a food product, and
mixing of the
gravy composition and food product to provide the pet food composition.

[0062] The dry ingredient composition, protein-containing composition, and
alginate
composition are mixed together to provide a homogenous mass referred to herein
as the
first mixture. The suitably-homogenous first mixture is then pumped to a
helical static
mixer fitted with a t-pipe at the inlet. The remaining open port of the inlet
is connected to
a pump that meters the setting composition into the center of the static
helical mixer at the
inlet. The metered first mixture and setting solution are combined and mixed
in the helical
static mixer, at a ratio of 10 parts first mixture to 1 part setting
composition, to initiate the
calcium ion induced gelation reaction. The folding action of the helical
static mixer also
produces a striated, meat-like appearance observed in the food product.
[0063] In one instance, the product of the gelation reaction is extruded
from the outlet
of the static mixer and cut to the appropriate size with a variable speed
rotary knife,
providing food products of variable length. In another instance, the product
of the gelation
reaction is extruded from the outlet of the static mixer and conveyed to a
multi-dimensional dicer, where both length and width are altered to fit the
food product
requirements.

[0065] In one instance, the food product strips or chunks (depending on the
processing), are combined with gravy, and optional inclusions (e.g., potatoes,
carrots, peas,
peppers), each according to their assigned formula amounts, and mixed by means
of a
single, double, or planetary mixer with a paddle attachment. When mixed to a
homogenous mixture, the mixture is pumped to a can line seamer/filler by means
of a
pump and the cans are processed according to conventional can line
specifications. In
other instances, the food product strips or chunks are deposited directly into
the can first

followed by deposition of a mixture of the gravy composition and inclusion
ingredients.
The canned products are then processed in a standard retort process.
[0066] In another instance, the food product strips or chunks (depending on
the
processing), are combined with gravy, and optional inclusions (e.g., potatoes,
carrots, peas,
peppers), each according to their assigned formula amounts, and mixed by means
of a
single, double, or planetary mixer with a paddle attachment, and the mixture
is flash
frozen.
[0067] In yet another instance, the food product strips or chunks
(depending on the
processing), are combined with gravy, and optional inclusions (e.g., potatoes,
carrots, peas,
peppers), each according to their assigned formula amounts, and mixed by means
of a
single, double, or planetary mixer with a paddle attachment, and the mixture
is transferred
to appropriate plastic bags and vacuum-cooked according to sous-vide methods
known in
the art.
[0068] In another variation, the methods of the present disclosure are used
to prepare
food products in a form suitable for inclusion in a hash-type or hybrid-type
pet food
composition. In this instance, the dry-ingredient composition, protein-
containing
composition, and alginate composition are mixed together to provide a
homogenous mass
(referred to herein as the first mixture) in a mass in a double or single
ribbon mixer,
horizontal mixer with a sigma blade, or a planetary mixer. In this instance,
however,
while the mixer is mixing the mixture, a steady stream of the setting solution
is added to
the mixer, initiating the calcium-ion mediated gelation reaction and causing
the mixture to
form a firm texture. The mixing is continued, thereby processing the product
of the
gelation reaction into food product pieces to the desired size.
[0069] Once the desired size is obtained, the gravy and inclusions can be
added to the
mixer and the mixture is mixed until homogenous. Once fully mixed, the mixture
is
pumped to a can line seamer/filler by means of a pump and the cans are
processed
according to conventional can line specifications, and the canned products are
processed in
standard retort processes.
[0070] In another instance, hash-type or hybrid-type food composition is
flash frozen.
[0071] In yet another instance, hash-type or hybrid-type food composition
is transferred
to appropriate plastic bags and vacuum-cooked according to sous-vide methods

pork lung. The ground meat was mixed to provide a substantially homogenous
mixture.
[00102] The amounts by weight % of the chicken, pork liver and pork lung in
the pet
food composition are in Table 26.

[00103] The Nutritional analysis of Food Compositions C and D are listed in
Table 27.

[00104] Food Composition C was prepared by mixing the dry ingredient
composition,
protein-containing composition, and alginate composition to provide a
homogenous mass.
The homogenous mass and setting solution were combined and mixed.
[00105] A gravy composition was prepared by mixing the ingredients in Table
28.

[00106] A gravy composition was added to the homogeneous mass and mixed. The
mixture was dispensed into cans and processed by a standard retort process.
[00107] Food Composition D was prepared by mixing the dry ingredient
composition,
the liquid composition, and the protein-containing composition to form a
homogeneous
mass. A gravy composition was added to the homogeneous mass and mixed. The
mixture
was dispensed into cans and processed by a standard retort process.
[00108] Prior to retort, Food Composition C formed a product having a well-
defined
structure and Food Composition D formed a dough-like mass having no defined
structure.
Using a TA-TX2 texture analyzer with a TA-65 Multi-Puncture ring (Texture
Technologies Corp), the texture of the food compositions was measured. The
results

(Table 29) show that Food Composition C with the potassium alginate had a
harder texture
than Food Composition D without the potassium alginate.

[00109] Food Compositions C and D were visually compared against a
commercially-
available chunk-and-gravy product (Food Composition CG). The Nutritional
Analysis of
Food Composition CG is in Table 30.
TABLE 30: NUTRITIONAL ANALYSIS
Ingredient Food Composition CG:
Amount-Dry Matter Basis
Protein 32.0 %
Fat 19.5 %
Carbohydrate (NEE) = 41.0 %
Crude Fiber 3.0%
Calcium 1.1 %
[00110] Food Composition CG had uniform pieces with smooth outer surfaces and
no
inner or Outer striations. The piece sizes were very fine. Food Composition C
had
irregularly-shaped pieces with inner and outer striations, giving the
composition a more
meat-like appearance.
[00111] The methods disclose herein can therefore be used for producing formed
meat
pieces, particularly retort-stable formed meat pieces of variable size, shape
and
composition for the production of food compositions comprising those formed
meat
pieces.
[00112] As used throughout, ranges are used as shorthand for describing each

value that is within the range. Any value within the range can be selected as
the terminus
of the range. In the event of a conflict in a definition in the present
disclosure and
that of a cited reference, the present disclosure controls.
